Description
In the Linux kernel, the following vulnerability has been resolved:
drm/tegra: Fix a possible null pointer dereference
In tegra_crtc_reset(), new memory is allocated with kzalloc(), but no check is performed. Before calling __drm_atomic_helper_crtc_reset, state should be checked to prevent possible null pointer dereference.
